17 Claims. (Cl. 242-843) This application is a substitute for abandonedggfslication Serial No. 584,296, filed March 23,

This invention relates to reeling mechanism for crank operated reels ofvarious types, and more particularly to fishing reels of the combinedautomatic click and anti-backlash type.

Heretofore, in the use of the conventional star drag reel, for certainwell known reasons, it is common practice to preset the drag tensionbefore casting the line. In the event of an unexpected, sizable catchmany hundred yards of line may be carried out by the fish, which reducesthe convolutional core diameter on the spool, thereby greatly increasingthe ratio by which the drag tension was previously set. In order toavoid breaking the line, such increased tension is of course releasedwith ease while the crank is at rest, however, it will be understoodthat subsequent rewinding will require an equal amount of increased dragtension which obviously is difficult to adjust simultaneously with thereeling-in operation. Therefore, it is an object of the presentinvention to transpose the crank and the star adjusting wheel andarrange the associated parts thereof in a more convenient relationship,so as to greatly facilitate the anglers right hand in cranking in theline and making simultaneous adjustments of the star wheel withoutretarding effect in the operation.

The primary object of this invention resides in the construction of adriven and driving element, the latter including a telescopic shaftassociated with a compression spring for forcing the elements intofrictional engagement and thrust transmitting members carried by theshaft and associated with the crank, the ratchet and pawl and adapted toforcibly separate the clutch elements on relative rotational movementbetween the crank and the pawl, thus automatically engage or disengagethe clutch elements on forward or retrograde rotational movement of thecrank respectively.

Another important object of this invention resides in the provision ofmeans by which a greater diaphragmatical frictional surface isobtainable in a comparatively limited space by the employment ofmultiple disk, male and female units, associated with the spool drivepinion gear. This type of clutch mechanism afiords the advantages ofbeing extremely resilient and flexible with respect to line control, andthe same may be instantly and completely declutched without draggingeffect for free clutch action, thus providing a reel structure that isfree from the usual axially This application July 2 shiftably engaginggears, keys or lugs between the crank and the spool.

In using a rod and reel in the customary manner, the angler after eachcast immediately shifts the rod to the left hand, thereby freeing theright hand to manipulate the various line-controlling features of thereel. Therefore, a meritorious object of the present invention residesin the provision of means including a combined click and backlashpreventer, disposed on the right hand side of the reel, so the same maybe adjusted by the anglers right hand as the line is being paid out andwhich preventer, in use, will not interfere with the line winding-inoperation of the spool, the same taking effect automatically when thereel is used in casting.

Other objects of the invention will become apparent as the detaildescription thereof proceeds.

Referring to Figs. 1 to 10 inclusive, there is illustrated a preferredform of the improved cranking mechanism applied to the driving system ofa conventional type fishing reel.

It is seen that such a reel includes a recessed head plate A to which isconnected the usual pillars I and the reel seat 2, the latter partsextending to the tail plate, not shown. 1

Attached to the opposite side of plate A, by means of. screw 3, is anoutwardly curved cover or ratchet plate 4 having an inwardly projectingstud support 5. Supported on the stud 5 is the spool B, having a tubularhub 6 of hexagon in- 'cally slotted as at 22 to provide ternal formreceiving a shaft I of corresponding external form which is providedwith a co-axial socket seated over the stud for rotation. A crank C ismounted on the plate A for operating the spool B.

With reference to Figs. 1, 2 and 3, it will be seen that the head plateis formed with an eccentric and concentric opening which intersect eachother. The outer face of plate A is correspondingly recessed as at 8 forthe peripheral support of the ratchet plate 4 which is suitably inlaidin said recess 8, thus providing a gear chamber for the pinion gear Dand the clutch unit E. Screws 3 are passed through apertures in theplate A and threaded in registering threaded apertures of the bridgeplate 9 disposed on the inner side thereof, along with the reel seat 2which'is also provided with corresponding threaded apertures for thesupport thereof.

In the embodiment of the invention, selected for illustration in Figs. 1to 9 inclusive, and referring first to Figs. 2 and 3, it will be seenthat the ,central portion of the bridge 9 is provided with acounter-bored bearing it, wherein is journalled the headed end Illa of aclutch frictional adjusting bolt or shaft l I, the opposite end of whichshaft is screw-threaded l2 and flattened l3 for fixed reception of astar adjusting wheel It, secured thereto by a hexagon cap nut i5 whichis screw-threadedly engaged therewith.

The ratchet plate '5 is also provided with a central bearing 16, whereinis journalled a tubular shaft H which telescopes over shaft ii andtogether with the assembled parts comprises the driving element F of theclutch unit E.

Shaft i1 is formed with a reduced inner end it and the opposite endthereof is of enlarged inner diameter, thus forming a cylindrical recessadjably, the latter disks are dovetailed together as an integral unit bymeans of the flanges 39 bein press-fitted in the groove 38, whereby theoffset peripheral portion of the fiber disks are interlocked andrestrained against distortion from diaphragmatical action thereof, so asto increase the combined rigidity of the united gear-toothed peripheryand thus render the diaphragmatical area thereof more yieldable toresilient clutch action.

In assembly the disks 21, 28 and 29 are alternately interposed withrespect to the oflset disks cent an ofiset wall and internal andexternal shoulders l9 and 20, respectively. The shoulder I9 providesabutment for the compression spring 2!, and the larger diameter thereofis diametrikeyways for internally projecting keys of a star-shaped plate23, hereinafter to be described. An adjusting nut 24, formed withdiametrically disposed lugs 25, entering the slots 22 for screw-threadedengagement with the threaded portion l2 serves to adjust the compressionresistance of the sprin 2! between the shoulder l9 and this nut 24, on

relative rotational movement of the star wheel It.

As shown in Figs. 2 and 3, the reduced diameter l8 afiords a series ofsplines or serrations 26 which drive the disks 21, 28 and 29, made ofspring brass or other suitable resilient material and formed withinwardly projecting splines 30 engaging the splines 26.

There is provided a female driven clutch element G of special design,including resilient disks 31, 32 and 33, made of fiber or other suitablefrictional material which are identical in form, each provided with acentral aperture 34 and an offset gear-toothed periphery 35; such offsetforms external and internal shoulders 36 and 3! respectively. The latterdisks afford a diaphragmatical area which is reduced in thickness, thusproviding a second or innermost shoulder 31a and an annular deep recesswhich permits axial shifting clearancefor said metal disks therebetween.Adjacent the periphery of said shoulder 36, is provided the outer facethereof with a rectangular shaped annular groove 38 and the oppositeface thereof is provided with a second recess which forms an annularrectangular shaped tongue 39 conforming to the groove 38 whereby, inassem- II, 32 and 33 along with the spacer rings 40, 4| and the clickring 42, which ring is provided with click teeth 43. 7

Click ring 42 is also provided with internal splines and press-fittedover the splines 28, thus securing the metal disks 21, 28 and 29 againstaxial movement with respect to the tubular shaft IT.

A second shoulder 44 on bolt I i abuts an apertured annular thrust plate45, of equal diameter to the internal shoulder 31 also provided with anannular groove 38' corresponding to the flanges 35 whereby this plate isunited with the driven element in the same manner as the ofiset disks. Aretainer washer 46 is press-fitted over the bolt ll, abutting the plate45, so as to prevent axial displacement of the driven element duringfree clutch action, at which time the spacer rin 68 serves as a bearingor guide for the outer side of element G. the latter being free to idlyrotate on the inner end of bolt II and the ring 40, except as it may befrictionally driven. Obviously, natural working stresses of the fiberdisks, when under thrust pressurepis such as to retain the parts intheir proper place and their gear teeth 35, being in constant mesh withgear D, prevent accidental rotational displacement thereof.

It will be observed that a clutch unit has been provided including maleand female units, wherein the male unit is comprised of resilient diskscentrally supported in spaced relation, and the female unit consists ofspaced resilient inwardly extending disks, each supported by itsperipheral diaphragmatical area. The disks are thus effectively mountedand supported for combined resilient or diaphragmatical clutch action inan interlocking relation, yet they may be efliciently assembled ordisassembled. This also facilitates and improves upon the fabrication ofthe female unit. Obviously, the rotation of this unit during the castingoperation provides a. slight inherent resistance which tends tosynchronize the spool speed with that of the line, thus assist inpreventing backlash.

It will be seen that there is provided shaft H with an annularcup-shaped ratchet pin or pawl carrier-member 41 which is centrallybored to fit over the tubular shaft l1 and counter-bored to receive theouter end of bearing -l 6.

The end of crank C, opposite its free end, is formed with a ring-likehub 48 which serves as a thrust transmitting member, and the carrier 41is provided with an annular O-shaped axially projecting collar 49 havingan arcuate section omitted, thus forming therein spaced stop shoul-'ders 5|] and 5|; this collar portion receives the ,crank and its hub 48for limited rocking movement therein and between the shoulders 50 and5|. This hub 48 is retained in the carrier 41 by means of the plate 23and screws 52 which are passed through counterbored apertures in thecollar 49 and thre'adedly engage the registering threaded apertures inthe plate 23, the latter of which in this instance constitutes a ballcase which is provided with three ball retaining channels 53, spaced 120apart, for the clutch actuating steel balls 54.

As shown in Figs. 2, 5 and '7, the outer face of crank hub 48 includesthree concave ball sockets 55 of the same curvature as balls 54, alsospaced 120 apart. Integral keys 55 of the cage 23 enter the'slots 22 fordriving shaft l1, yet permit axial movement thereof. The shafts outerend is screw-threadedly engaged with a knurled adjusting nut orthrusttransmitting member 51, resting I under the urge of spring 2| on theballs 54. This nut 51 is recessed, wherein is provided an annular circleof axially extending radial teeth or serrations 58.

Diametrically opposite the stop shoulders 50 and 5|, the collar portion49 is provided with a socket, receiving a detent pin 59, having awedgeshaped end conforming in shape to and abutting the serrations 58.Adjacent this pin 59, the collar 49 is provided with a bore which isintersected by the peripheral path of hub 48, wherein is mounted foraxial movement a ratchet pin or pawl 50 having a beveled end 5|, and theopposite end thereof affordsa socket which receives the right angle bentover end of a circular spring 62 that surrounds the ball cage 23 andpasses through the aperture detent pin 59.

Spring '62 is so arranged that its ends tend to laterally or axiallyseparate, thereby functioning to urge the detent pin 59against theserrations 58 while its opposite end co-acts with the pawl 60 and theinclining U-shaped indentures or ratchet teeth 63, so as to preventretrograde movement of the carrier 41.

As shown more clearly in Fig. 4, the upper side and outer end of pawl 60is flatted as at 64 thus forming a shoulder 65, and the lower peripheralcontour of ball cage 23 at this location is provided with acomplementary fiat bearing surface 64' which abuts the flatted surface64, thus preventing accidcntal rotational displacement of the pawl 60when the periphery of hub 48 is shifted or rocked in operation. As shownin Fig. 5, numeral 65 indicates an arcuate recess in the periphery ofhub 48 which provides an opening for the shoulder 65 to enter when thepawl 60 is functioning as a ratchet pin or pawl in the conventionalmanner.

With reference to Figs. 2, 3 and 9 it will be seen that the drivenclutch element G carries an offset blade spring 61 havin an integralclick-head 68, and the radially outer end thereof is securely attachedto the plate 45 by suitable rivets 69. This plate 45 is recessed as at10 so that the head 68 is free to coact with the click teeth 43 bydropping from tooth to tooth when the driven clutch element G isrotating with respect to the driving element F, as when functioning as adrag, thus producing suitable clicking sound which indicates the valueof frictional resistance being produced by the clutch unit E..

Assuming the clutch to be engaged (such position being shown in Figs. 2and 4), therefore previous to the disengaging operation, the balls 54are seated in their respective sockets 55, as shown in Fig. 2, and thecrank and its hub 48 are moved in the retrograde direction of travel asindicated by arrow 1|. Obviously, due to the spring 2| such movementtends to drive the, carrier 41 and its assembled parts, includin itspawl 60, in the same direction of travel until the latter coacts withone of the ratchet teeth 53, thus re- C abuts the-shoulder 5|.

straining further movement of the carrier 41, yet the hub 48 and itssockets 55 continue to rotate with respect to the channels 53consequently forcing the balls 54 out of their sockets 55 against theadjusting nut 51 which in turn shifts the shaft l1 longitudinallyoutwardly, thus compressing the spring 2| which is of suflicient lengthand suitable resiliency to permit axial shifting of the metal disks 21,28 and 29 from the fiber disks 3|, 32 and 33 respectively. Obviously,the full thrust load of spring 2| is transferred from the latter disksand absorbed by the assembled parts including the adjusting nut 51,balls 54, hub 48, carrier 41 and the bearing l5, thus producing africtional resistance between the latter, and the bolt head Illa, whichparts serve to retain the clutch unit E in its disengaged or free clutchoperating position.

The crank C still proceeds in its relative movement until it abuts theshoulder at this position the balls 54 register and seat in the shallowdetent dimples 12 which prevent accidental displacement of the crank C.

As shown in Fig. 3, the click teeth 43 are moved axially outward fromthe click-head 58 so that the apex of teeth 43 delicately contact thehead 68 as it rotates about the teeth 43 thus producing a slightclicking sound which indicates the extent of value of a slightrotational resistance therebetween, which is employed to controloverrunning of the spool through the medium of the driven clutch elementG, and the pinion gear D.

Obviously, there is provided a peripheral knurled nut 51, adjustable bythe anglers right hand which, when adjusted, will effect the limits ofoutward movement of shaft l1, and in turn its connected teeth 43 withrespect to the revolving head 68, thus adjusting the'aforesaidresistance therebetween so that the angler may control the casting speedof the spool and thus synchronize its speed with that of the bait andline.

Referring to Figs. 3 and 8. In the normal cranking operation, the crankhub 48 is of course rotated in the right hand direction as indicated bythe arrow 13, which movement automatically engages the clutch unit E fordriving the spool B. It will be seen that the pawl 60 is arranged sothat the shoulder 65 and its opposite beveled end 6| wedge between oneof the inclining ratchet teeth 63 and the inner peripheral marginal faceof the hub 48, so as to detain rotational movement of the carrier 41only until the arm of crank During this limited movement the balls 54slide into the sockets and thus engage the clutch; co-incidentally thearcuate recess 66 registers" with the ratchet pin which permits normalpawl action with the ratchet teeth 63.

Shaft I1 is of suitable length, relative to the depth of sockets 55, topermit its assembled disks 21, 28 and 29 to frictionally seat upon thefiber disks 3|, 32 and 33, the latter of which then absorbs the fullpreset pressure load of spring 2|, thus relieving all thrust on theballs 54 and all torsional resistance due to spring thrust betweenbearing l6 and the bolt head I Ila, the latter of which is then free torotate as a trunnion in the bridge 9.

It will now be seen that flange 14 serves to prevent outward axialdisplacement of the bolt H and its connected parts and that the entirecranking assembly is free to 'frictionally drive the clutch element Gand the spool B through the medium of gear D and the shoulder 5| on thecarrier 41.

The convolutions of spring 2|, being in slight contact with theperiphery of bolt ll so as to provide friction load suitable to preventaccidental rotational displacement, yet permit manual adjustmentthereof.

When it is desired to increase frictional resistance of the clutch unitE simultaneously with reeling in the line, the knob 15 is held by theoperator's thumb, forefinger and the ring finger while permitting theindex finger to extend slightly outward so that, on its upward swingingmovement, it passes through and engages the star wheel M, thecounter-balance end of crank C being eliminated for this purpose.Obviously this operation will effect intermittent rotational movement ofthe star wheel It with respect to shaft I! and its connected shaft Hand, in turn, its right hand threads l2 will effect inward axialmovement of thenut 24 thus increasing the urge of spring 2! and in turnthe frictional resistance of the engaged clutch unit E.

The improved reeling mechanism may be applied to, various types of reelsand the parts are comparatively few, there being a'two-purpose crank, atwo-purpose clutch spring, a two-purpose click, a two-purpose pawlspring, and a threepurpose pawl, all of which parts are effectivelymounted and they are simple in form, therefore easy to assemble.
